Production process for metal composite plates

Abstract

The invention aims to provide a production process for metal composite plates, which can effectively meet the requirement of producing various metal composite plates in small batches. The production process is characterized in that: metal plates with the same material or different materials are cut, rolled and welded into metal pipes; the metal pipes are combined together to form metal composite pipes after the composite surfaces of the metal pipes are cleaned by mechanical processing; the metal composite pipes are subjected to hole enlargement, expanding and flanging processing, rolled and composited by a duo mill under heat condition, and cut into composite metal plates; and the composite metal plates are rolled on a four-high mill into the metal composite plates meeting the requirement.

Description

Technical field: [0001] The invention belongs to the technical field of metal composite plate rolling, and in particular relates to a metal composite plate production process. Background technique: [0002] At present, there are mainly the following metal composite panel production processes: [0003] 1. Explosive cladding - rolling process [0004] Explosive cladding-rolling process is to carry out explosive cladding after surface treatment of the metal plates to be clad. The metal plates to be compounded are closely compounded by using the high energy generated by the explosive explosion, and then rolled after heating to become a double-layer metal compound plate. The disadvantages of this process are: (1) the process is complicated, the surface treatment of the metal plate is difficult, the product quality is unstable, and the yield is low; (2) the explosive composite process has low efficiency, high degree of danger, and great impact on the environment; (3) due to The...

Problems solved by technology

The disadvantages of this process are: (1) the process is complicated, the surface treatment of the metal plate is difficult, the product quality is unstable, and the yield rate is low; (2) the explosive composite process has low efficiency, high degree of danger, and great impact on the environment; (3) due to The high-energy impact of the explosion affects the metal structure

The disadvantages of this process are: (1) the smelting of two metals is required at the same time, which has high labor intensity and has a great impact on the environment; (2) the thickness of the two metal plates is not easy to control and the yield is low; (3) the production process is not flexible , low efficiency, not suitable for small batch and multi-variety market demand; (4) Large plastic processing equipment is required

In this method, the surface treatment process of the metal strip is complicated, and the bonding strength of the two metals is low, which is only suitable for the production of bimetallic strips of metal materials such as aluminum, copper and steel.

[0009] In addition, bimetallic plates can also be obtained by spraying, powder sintering, vapor deposition, electrolysis, and liquid-solid composite methods, but none of them can be mass-produced.
